Retired Army colonel Douglas Macgregor has always been a bomb-thrower. His 1997 book on the future of the U.S. Army, Breaking the Phalanx, was equally loved and hated by those inside the service. An innovative battle tactician who some saw as arrogant, he’s one of those guys who colors just a little too much outside the lines for the Army’s liking. But given his skill set, his latest offering in Foreign Policy magazine — where he recommends cutting some $275 billion a year from the Pentagon’s budget (about 50%) — is well worth a look. Makes my recent piece on saving $1 trillion over a decade — $100 billion a year, in other words — look pretty darned hawkish.
